PLOW.

Specification of Letters Patent.

Patented Aug. 22, 1905.

To. a. 10/1/0722, it may concern:

Be it known that I, MIcnnL Z. THOMAS, a citizen of the United States,residing at Pueblo, in the county of Pueblo and State of Colorado, haveinvented certain new and useful Improvements in Plows, of which thefollowing is a specification.

This invention relates to plows, and has for one of its objects toprovide a simple, durable, compact, and economically-constructed deviceof the character named.

Another object of the invention resides in the employment of anattachment arranged with relation to the plow for automatically clearingthestructure of weeds, grass, and other accumulations.

A still further object of the invention resides in means for permittinga cushioning action between the wheel of the plow and the plow-frame.

Vith these and other objects in view the present invention consists inthe combination and arrangement of parts, as will be hereinafter morefully described, shownin the accom panyin g drawings, and particularlypointed out in the appended claims, it being understood that changes inthe form, proportion, size, and minor details may be made within thescope of the claims without departing from the spirit or sacrificing anyof the advantages ,of the present invention.

In the drawings, Figure 1 is a. perspective view of the plow embodyingmy invention. Fig. 2 is a side elevation of the side opposite to thatshown in Fig. 1, illustrating in dotted lines the movement of theclearing-blade with relation to the colter. Fig. 3 isa rear elevation.Fig. 4 is a sectional view on the line a a of Fig. 2. Fig. 5 is asectional view on the line Z) Z) of Fig. 2. Fig. 6 is a detailperspective view of the colter-clearer, and Fig. 7 is a detailperspective view of one of the casings for inclosing a coil-spring.

Referring now more particularly to the accompanying drawings, thereference characters 1 and 2 designate the usual form of plowhandles,having one or more of the usual cross or brace pieces 3.

member 2 and secured in any suitable manner thereto is arranged theplow-beam 6, the numeral 7 indicating the standard, which in thisinstance has its upper end 8 bent at a right angle to its body portionand fitted between the under side of the beam and a plate Intermediatethe handle 9, bolts and nuts 10 and 11, respectively, passing throughthe beam and the plate to se-v curely-retain the standard in position.Of course I do not limit myself to the securing of the upper end of thestandard to the beam in the manner shown and described, it being obviousthat other means may be employed, if desired.

' Secured to the lower end of the standard 7 and the handle 2 isarranged the ordinary form of landside element 12, thesame being securedupon the standard and handle by any suitable meansfor instance, thebolts13, as shown.

A moldboardl l: bridgesthe tapered end 15 of the landside and the lowerend of the handle l, a bolt 16 piercing the moldboard and said handle tosecure the former at one side, while its opposite side is secured in anysuitable manner. As a matter of fact, thelandside and moldboard may beformedot a single piece of material.

Disposed at therear of the beam-Band secured to the outer face thereofby means of a bolt and nut 17 and 18, respectively, or other suitablemeans is an axle-hanger 19, which inclines slightly toward the rearof'the plow and whose intermediate portion is pierced by the bolt orother element 20, which passes through the handle 2 of the plow, a nutor other means being screwed or otherwise secured upon the free end ofthe element 20 for a purpose well understood. Thus it will be seen thatthe hanger 19, having the aforesaid connections with the beam and handle2, serves to brace them and prevent undue strain upon one with relationto the other. Y

Another aXle-hanger22, whose upper end is preferably bent at a rightangle, as at 23, designed to fit upon the upper surface of the handle 1,is disposed directly opposite and lies in the same plane with theaforesaid hanger, the hanger 22 being firmly secured upon itscorresponding hanger by means of the bolt and nut 2a and 25,respectively, or in any other suitable manner. Each of these hangers isprovided with a slotted journalbearing 26 at its lower free end, whichlie in substantially a vertical plane with relation to each other andthe resting position of the plow.

An axle 27 has its ends 28 rounded, squared, or otherwise formed andjournaled in thejournal-bearings 26 of the axle-hangers 19 and 22, theaxle having a bent crank portion 28 for a purpose presently understood,there being a toothed or other Wheel 29, fixedly secured upon the axleadjacent the bent portion 28.

Formedin the under side of each of the plow-handles 1 and 2 is a recessor depression 30 and 31, respectively, both of which receive the upperopen ends of tubings or casings 32 and 33 of any suitable material,whose lower ends are bifurcated, as indicated by the reference character34, and by reason of which the lower ends thereof may embrace oppositeends of the axle 27, there being a coil-spring or other flexible means35 arranged Loosely or otherwise fitted at one of its ends upon the part36 of the bent crank portion of the axle 27 is an arm 37, providedintermediate its length with a slot 38, arranged longitudinallytherewith and working upon a suitable support or projection 39, securedto the standard 7, with its free end preferably enlarged, as indicatedby the referencecharacter 40, the enlarged portion of the arm having itsedges preferably sharpened to rid the colter 41 of roots, weeds, orstubble which may accumulate thereon in plowing the ground. It will beseen that the knife portionthat is, the enlarged portion 40is offset toone side or laterally ofthe arm by reason of the angular bend 42 andthata spacing-collar or sleeve43 isloosely fitted upon the projection orsupport 39 and disposed between the standard 7 and the inner face of thearm 37 at its juncture with the longitudinal slot of the latter, thesaid collar taking up the space caused by the angular bend 42 andinsuring a square meeting engagement of the inner side of the knifeportion or clearer with the colter, thereby efliciently carrying out thepurpose for which it is designed. As shown in the drawings, this collaror sleeve 43 is of greater internal di-' ameter than the support orprojection 39 for the purpose of reducing friction and permitting a freeand easy movement of the arm. In other words, if the collar or sleevewere fitted tightly upon the projection or support .39 the movement ofthe arm would not be as free as desired, and, furthermore, as shown inthe drawings, there is absolutely no danger of .corrosion or clogging ofdirt or other foreign the top surface of the plow-beam. This bentportion of the colter is not altogether essential and may be omitted, ifdesired. The colter, however, is preferably secured to the beam in suchmanner as to render it adjustable-for instance, by providing the samewith an elongated slot 45 or the equivalent permitting of a verticaladjustment through the assistance of a bolt or other element 46 piercingthe beam and secured at its free end by means of a nut or the like 47.

Secured at their upper ends, preferably between the colter and standard,are arranged tines 48, the same being for a well-known purpose and inthis instance being secured to the beam by means of a plate 49 andsuitable fastenings 50.

From the foregoing description it will be seen that a highly efficientand rigid plow is produced and that as the axle turns in its bearingsthe bent crank portion thereof causes the arm and its blade to operatein a manner customary in the movement of a pitman, and thusautomatically and satisfactorily clearing the colter of foreign matter,causing the foreign matter to be deposited in the bottom of the furrow,the dotted lines in Fig. 2 of the drawings illustrating what ispractically a circular movement of the knife-blade over one side of thecolter. It will be seen also that my colter-clearing attachment maybereadily applied to any of the plows now in use.

I claim-- 1. A plow, including handles, a beam, a standard and a colter,said standard having an offset projection; an axle carried by the plow;

a wheel mounted upon the axle; and an arm secured to the axle andprovided with a slot intermediate its ends, whereby the arm may beslidably supported upon the projection of the standard, said arm havingan offset blade portion for engagement with the colter.
